SLIGHTLY ACIDIC HYDROFUSE PROCESSING METHOD Russian patent published in 2014 - IPC C11B3/00 

FIELD: food industry.

SUBSTANCE: method involves hydrofuse separation into fractions by way of an activator introduction into the hydrofuse, the mixture stirring and settling. One preliminarily determines the volume V_hf, water saturation coefficient K_w.hf, hydrogen index of initial hydrofuse pH_hf and isoelectric point of hydrofuse protein pH_is. If pH_hf parameter is more then 5.0 units (slightly acidic hydrofuse) hydrofuse is heated up to 90-95°C; the activator represented by orthophosphoric acid is gradually introduced in small portions; under control, the hydrogen index is conditioned to pH_hf value equal to 5. For water electrochemical activation one produces anolyte required for obtainment of pH value parameter corresponding to isoelectric state of protein pH_is that is determined from the formula: $$V_a=\frac{V_{hf}\cdot K_{whf}\cdot \left(5-p{H}_{is}\right)}{\left(p{H}_{is}-p{H}_a\right)},m^3$$ where V_hf - hydrofuse volume, m³; K_whf - hydrofuse water saturation coefficient, unit fraction; pH_a - anolyte hydrogen index; pH_is - medium hydrogen index corresponding to isoelectric state of protein in sunflower oil.

EFFECT: invention allows to simplify the processing process and enhance efficiency of phosphatides and oil extraction from hydrofuse.
